Responsible manufacturer, target gut health, moderately effective
I take probiotics for my gut health and feminine balance. These probiotics have a broad-spectrum of strains that benefit both areas, primarily the gut. The dose is a single, smooth capsule a day, but the capsule is large for a probiotic. Still, it's easy to swallow, has no taste and has a pleasant, light scent due to the pineapple. I take these probiotics with food and find some improvement in my GI issues but they do not eliminate gas. I have no side effects. So for me they are moderately effective. I like the Vitalibre company and line of products because they are made in GMP facilities, are lab-tested and non-GMO. Each bottle is printed with the Lot Number and Expiration Date, which is well over 2 years in the future. So, I have confidence in the ingredients and manufacturing of this supplement. At approx. 50 cents per day, they're affordable and definitely worth a try

Meh
On the fence if this has helped or not. Haven't really noticed anything and I've given it 2 months. Probably won't order again.

Fun probiotic
My favorite part about this one is that it’s a one pill dose. I take more pills than ideal so anything that only requires one pill is a selling point for me. As a probiotic, I’m giving it 5 stars for meeting expectations based on the listing even though it’s probably a 4 star product for me personally.
This comes in a surprisingly compact capsule. I’m not an expert of all the options available on the market currently but it’s one of the smallest shelf stable probiotics I’ve taken on top of only requiring one pill a day. There is a mild scent and taste that I assume is due to the pineapple powder. It’s not distinctly pineapple but it has a hint of the sharpness. That said, I didn’t find either the flavor or scent strong enough to be off putting.
Effectiveness is a little more nebulous. I didn’t have any negative effects and my gi tract seems to be running smoothly. 25 billion cfus is lower than what I find to be an optimal dose for my system but I wanted to try it out to see if 50 billion was overkill. I think the higher dose is a better fit for me because while things were fine on this, I feel like it did see even more improvement at my prior level. That said, this could be a great option for someone who wants a little more than a low, baseline dose but may be too sensitive for the 50 billion and higher options.
Value is decent. It’s not the absolute cheapest but hangs out in the bottom half of the price per dose spread I’m familiar with.
